To all wwm 'it may eoncem:

Be it known that I, Rounn'r E. L. Homme, a citizen of the United Stntee;residing et Aurora, in the county ol" liano und Stute of lllinoisJ haveinvented eertuin new und uneul Improvements in lunips; of whieh thefollowing is n speeiiienl'iou. reference being had to theaeeoulpunyiup?` drawings.

illy invention relates-to pumping. .zppzij rutns; und Imrtieulurly topumps designed for use in rzlisinpl walter .troni deep wells olf Smellhere where the water doer-1 not rino suiiieientlly neur to the suri'aueto he drztwn out by ineens ol :l suction pulnp.

lt has for its ohjeet to provide u new und improved double-:loting pumpso constructed and operutinpr ur; to deliver Huhstuntiullv :i uniforni'volunie ol" wnter on either the u'p or the down stroke; elmo to'provide a pump adapted to he' plnved in the bore. of the wel]ln'elferuhly helow the level of the water therein und so eonntruetedthat the vulves und pis-Lou '.inu v ezusily he drawn out ot the wellAio'r repuirs without removing the puntp piping und working hui-rel fromthe well. l aeeolnplieh these objects :is illus-l trated in' thedrawings and hereinni'tzer described.

that I regard as new is set forth in the claims.

45 indicates a valve-cage at the upper end of the piston-rod 2t) andpreferably secured thereto b v being y crewed thereupon. xaid valve-cagecarriesl a ball-valve 'lt seated at the upper end ot' the piston rod 29and acting as a checkr'alvc to prcventthe downflow of watertherethrough. As shown in Fig. l. the upper end ot' the vvalve-cage l5is provided witlra screw-tlireadcd boss 47 for the convenient attachmentthereto ot the rod used in withdrawing the piston 'from the well.

48 indicates the piston, which is fitted inl the cylinder 15 and isconnected at its upper andlower ends, respectively, with the piston rods2S) and l2 in vthe manner hereinafter described. As best shown in Figs.l and 2, the piston 4S is provided with a central passage 4f) with whichthe upper piston-rod 2.() communicates. The lower end of said passagel!) opens laterally and communi; cates with a transverse passage 50which' opens into the cylinder 15 below the piston, as shown in Figs. land 5. Said cylinder is also provided witli\ one or more verticalpassages 51, the lower ends of which coinniunicate with the lowerpiston-rod 112, as shown in Fig. 2. .'lhe upper ends of said passages 51extend through the upper end of the piston, as shown in Fig. Q,- and arenormally closed by a. valve-disk 52 which v rests thereupoii, beingyicldizigly held down in place by it spring 53 between' rsaid disk andthe collar/13, as shown in Figs. 1 and 2. lt will thus 'be seen thatwater may flow upward through the lower piston-rod 42 and passages 5l,entering the cylinder l5 above tbe pistou` where it: will be held b ythe checkvalve 59..

5l indicates pat-kine' between the piston is of such character as topack the piston and the cylinder when said piston is moved lthe 'waterwill be held above the connection with metallic rings 56, which hold thepacking in place. Rings 57-58 are secured upon one end of the piston sothat the pai-king may he compressed as desired or removedwhen'nccessary.

The operatioiris as tollow s:-Assuming the piston to be below the levelof the water in the cylinder 15, when the piston is raised piston by thecheck-valve and will be lifted as the piston moves up, flowing throughpassages )5 and above the valve 26, which will be lifted by theiipwardly-moviiig body ot' water. The lower portion ofl the pipe lb willtherefore bc filled with water, which `will be held therein by means ofthe valve will lill the cylinder 15 below Vthe piston,-

either flowing in by gravity or being drawn up .by suction as the pistonrises, and will be held therein by means of the checkvalve 8S, whichdrops as soon as the upward flow ot' water ceases. The piston being thenmoved downward, the water below the piston will be t'orced up throughpassages'50 and 49 through the vupper piston-rod 9.9 to the pipe lll.passing the valve lli. which is li't'ted by the pressure of theupwardly-flowing water. It will thus be seenk that when the piston movesupward the water in the cylinder 15 above it is discharged into the pipe16, while when the piston moves downward the vater belowit in thecylinder 15 is in like m'anner discharged into'the i e 1G, and as thesevolumes are substantial y equal it follows thafa practically uniformflow of ,water is securedfIn practice the working barrel or cylinder 15isl placed a considerable distanceperhaps a hundred feet or morebelowthe surface of the ground and preferably below the normal level of thewater in the well, and the valvecaLe `l5 is connected 'by a rodwith'some suitable reciprocating mechanism for actuating it'. y Q

By the construction described I provide an apparatus which mayreadilybe' placed in or removed `from tlie'well, and one which providesfor delivering a practically continuous and uniform volume of water inani-up- 'ard direction. I .also avoid the use pf tortu'ous waterpassages, as-the passages'"inmy appa ratus" are substantially straightandare eonliiiiious in an upward direction, S0 ,that there islessresistance to the'upward flow of water, thereby increasing theefficiency of the pump.

I wish it to be understood that while I have described my specific formof apparal tus with a considerable degree of particularity my inventionis not restrictedto the details of the constructioii shown and delI l)sel'ihed, eee t in sofar. as thea;- are spesaidupiston around saidcentral passage, saideially 'elaiinei as it includes .generically thesubjeet-niatter of the broader elainis. t f
